I-PFC ephezulu elawula ukunikezelwa kwamandla okutshintsha

I-PFC yintsingiselo yokulungiswa kwezinto zamandla, esetyenziswa ikakhulu ukubonisa ukusebenza kakuhle kwamandla ombane ngeemveliso zombane.Okukhona uphezulu umba wamandla, kokukhona uphezulu ukusetyenziswa kakuhle kwamandla ombane.

Kukho iindidi ezimbini ze-PFC: i-PFC esebenzayo kunye ne-PFC esebenzayo.I-Passive PFC ithatha ngokubanzi indlela yembuyekezo ye-inductance yokunciphisa umahluko wesigaba phakathi kwesiseko sangoku kunye nombane wegalelo le-AC ukuze kuphuculwe into yamandla, kodwa amandla e-PFC angenayo ayiphezulu kakhulu kwaye inokufikelela kuphela kwi-0.7 ~ 0.8;I-PFC esebenzayo yenziwe nge-inductance, i-capacitance kunye nezixhobo ze-elektroniki, inokufikelela kwi-0.99.Incinci kwaye inokufezekisa amandla aphezulu, kodwa ixabiso liphezulu kunelo le-PFC esebenzayo.

I-PFC ihlala isetyenziswa njengobonelelo lwamandla olusebenzayo kwiPC, kwaye iPFC inezi mpawu zilandelayo ubuncinci:

I-1) I-voltage yegalelo inokusuka kwi-90V ukuya kwi-270V;

2) Umbane wamandla omgca uphezulu kune-0.98, kwaye unenzuzo yokulahlekelwa okuphantsi kunye nokuthembeka okuphezulu;

I-3) I-PFC ye-IC ingasetyenziselwa njengombane oncedisayo, ngoko ke i-transformer yokulinda isoloko ingafuneki ekusebenziseni isekethe ye-PFC esebenzayo;

4) Imveliso ayiguquguquki kunye ne-voltage yegalelo, ngoko ke i-voltage ephumayo ezinzileyo inokufumaneka;

I-5) Imveliso ye-DC ye-voltage ripple ye-PFC esebenzayo incinci kakhulu kwaye ibonisa i-sine wave ye-100Hz / 120Hz (izihlandlo eziphindwe kabini zamandla).Ngoko ke, unikezelo lwamandla usebenzisa i-PFC esebenzayo ayifuni ukusebenzisa i-capacitor enkulu yokucoca umthamo.

I-PFC esebenzayo yenziwe nge-inductance, i-capacitance kunye namacandelo e-elektroniki.Inomthamo omncinci.Ihlengahlengisa i-waveform yangoku nge-IC ekhethekileyo ukubuyisela umahluko wesigaba phakathi kwangoku kunye nombane.I-PFC esebenzayo inokufezekisa amandla aphezulu - ngokuqhelekileyo ingaphezulu kwe-98%, kodwa iindleko nazo ziphezulu.Ukongeza, i-PFC esebenzayo inokuphinda isetyenziswe njengobonelelo lwamandla ancedisayo.Ke ngoko, ekusebenziseni isekethe ye-PFC esebenzayo, i-transformer yokulinda ihlala ingafuneki, kwaye i-ripple ye-voltage ye-DC yemveliso ye-PFC esebenzayo incinci kakhulu.Olu nikezelo lwamandla aludingi ukusebenzisa i-capacitor enkulu yokucoca umthamo.

Kutshanje siphehlelele i-2000W kunye ne-3000W yokutshintsha amandla ombane kunye ne-PFC.Ixabiso liluncedo kakhulu.Ixabiso eliphantsi kakhulu kunombane ofanayo kwimarike, kwaye ukusebenza kuzinzile kakhulu.Ukuba unomdla kuyo, nceda uqhagamshelane nathi.Enkosi!
